The device measures this differential voltage signal on commonmode voltages that can vary from 0 V up to 36 V, independent of the supply voltage.
The INA300-Q1 device features an adjustable threshold range that is set using a single external limit-setting resistor.
A selectable hysteresis feature enables adjustable operation of the comparator to accommodate the wide input signal range of 0 mV to 250 mV.
An open-drain alert output on the device can be configured to operate in either a transparent mode where the output status follows the input state, or in a latched mode where the alert output is cleared when the latch is cleared.
The device response time setting is selectable, which enables ...
